Caracterização geomorfológica e paleogeográfica da plataforma continental adjacente a foz do Rio Apodi-Mossoró, RN/Brasil

The brazilian marginal basins have a huge potential to generate and accumulate petroleum. Incised valleys which are eroded in response to a fall of relative sea level are related to potential reservoir as well, modern drowned-valley estuaries serve as harbors to petroleum and salt industries, fisheries, waste-disposal sites and recreational areas for a significant fraction of the world s population. The combined influence of these factors has produced a dramatic increase in research on modern and ancient incised-valley systems. This research is one expression of this interest. The integrated use of satellites images and high resolution seismic (bathymetry, sides scan sonar) was used on the Apodi River mouth-RN to characterizes the continental shelf This area is located at the Potiguar Basin in the NE Brazilian Equatorial Atlantic margin. Through bathymetric and side scan sonar data processing, a digital Terrain Model was developed, and a detailed geomorphologic analysis was performed. In this way was possible to recognize the geomorphologic framework and differents sismofacies, which may influence this area. A channel extending from the ApodiMossoró river mouth to the shelf edge dominates the investigated area. This structure can be correlated with the former river valley developed during the late Pleistocene sea level fall. This channel has two main directions (NW-SE and NE-SW) probably controlled by the Potiguar Basin structures. The western margin of the channel is relatively steep and pronounced whereas the eastern margin consists only of a gentle slope. Longitudinal bedforms and massive ridges also occur. The first are formed doe to the shelf sediment rework and the reef-like structures probably are relics of submerged beachrock-lines indicating past shoreline positions during the deglacial sea-level rise. The sub-bottom seismic data allow the identification of different sismic patterns and a marcant discontinuity, interpreted as the Upper

Influência espaço-temporal e fisiológica na absorção de nutrientes e elementos tóxicos por Eichhornia crassipes visando o uso adequado da sua biomassa: o caso do Rio Apodi/Mossoró - RN

This study aims to determine the amount of nutrients and toxic elements in aquatic macrophytes of species Eichhornia crassipes present in River Apodi/Mossoró - RN and check some of the possibilities of using the biomass produced, based on the influence of space - temporal and physiological absorption of nutrients by plants. For this, was determined: Leaf area, Leaf wet mass, Leaf dry mass, Real humidity, Apparent humidity, Ash, Total nitrogen, Crude protein, Calcium, Magnesium, Potassium, Total phosphorus, Sodium, Iron, Copper, Manganese, Zinc, Nickel, Cobalt, Aluminum, Cadmium, Lead and Total chromium at different times, 2 sampling points and 2 parts of plants (leaves and roots). The results show that the levels of nutrients, protein and toxic elements present in plant tissue of Eichhornia crassipes are influenced by spatial, temporal and physiological variability. In general, because the maximum values in the dry matter for total nitrogen (4.4088 g/100g), crude protein (27.5549 g/100g), total phosphorus (0.642 g/100 g), calcium (1.444 g/100g), magnesium (0.732 g/100 g), potassium (7.51 g/100 g), copper (4.4279 mg/100g), manganese (322.668 mg/100g), sodium (1.39 g/100g), iron (194.169 mg/100g) and zinc (3.5836 mg/100g), there was the possibility of using biomass of Eichhornia crassipes for various purposes such as in food animal, products production for human consumption, organic fertilizers, fabrication of brick low cost, and crafts. For all these applications requires a control of the levels of substances in plant tissue. Based on the levels of nutrients and crude protein, the younger plants (0 Month) would be best to have their biomass used. Moreover, one factor that contributes to the use of larger plants (6 Months), the levels of toxic elements which have significantly small or below the detection limit. Therefore, further studies quantifying the biomass produced/m2 at 0 and 6 months are needed for a more correct choice for the best time of harvest

Análise fitoecológica do manguezal e ocupação das margens do estuário hipersalino apodi/mossoró (rn brasil) a biotecnologia vegetal como alternativa para a cotonicultura

The mangrove is a coastal ecosystem of the big ecological importance, showing high fragility front by natural process and the human interventions in the coastal zone. This research has objective to analyses the relation between mangrove species distribution and geochemical parameters variation of the water and soil in Apodi/Mossoro estuary, located in the Rio Grande do Norte state north coastline. The results were obtained from floristic and structural analysis of the vegetation and Quick Bird satellite images interpretation (collected in 2006 year), manipulated with ENVI 4.3 and ArcGIS 9.2 software s. This estuary was characterized by to presents a gradient of the salinity around 40 kilometers extension, finding amount between 50 and 90 g/l-1. Will be identified the formation of the mix vegetation formation in the estuary mount, where the water salinity no show express wide variation on seawater (36 g/l-1), finding species: Rhizophora mangle L., Laguncularia racemosa (L.) C. F. Gaertn, Avicennia schaueriana Stap. & Leechman e Avicennia germinans L. Along of the estuary, have a streak formation of the vegetation composed by Avicennia spp. and L. racemosa. In high estuary, where the salinities value stay above 60 g/l-1, only A. germinans predominate in dwarf form. In this sense, the salinity is as a limiting factor of stress on the mangrove vegetation as it enters the estuary, this parameter should be taken into account when drawing up management plans and environmental restoration in the estuary in question

Biomonitoramento da qualidade da água e ações em educação ambiental em dois açudes da bacia hidrográfica Apodi-Mossoró, RN

Water scarcity is a reality for the inhabitants of the Brazilian semiarid region. The problem, in quantitative terms , is caused due to local climatic conditions due mostly to a water deficit. Qualitatively, results of multiple uses and resulting contamination by human activities. Eutrophication is presented as a threat to the sustainable use of water resources, in order to favor the predominance of dense populations of cyanobacteria, which can be potentially harmful to human health. The aim of this study is to understand the population dynamics of phytoplankton and cyanobacteria to assess water quality of reservoirs Santa Cruz do Apodi and Pau dos Ferros belonging to bacia Apodi Mossoró-RN . Water samples were collected monthly between October 2011 and May 2012 in reservoirs Santa Cruz do Apodi and Pau dos Ferros, in this latter , in Jan/12 we performed a diel profile . The abiotic variables obtained in the field and in the laboratory were: water temperature , dissolved oxygen , pH , turbidity , transparency , total nitrogen and total phosphorus . Phytoplankton samples were collected with a plankton net and bottle of Van dorn . Were performed : identification , quantification , calculation of biovolume , classification into functional groups and index calculation phytoplankton assembly ( Q ) , cyanotoxins were quantified by ELISA . Statistical analyzes supported the evaluation of the dynamics between biotic and abiotic factors. A questionnaire was conducted to examine the conceptions of the population, education professionals and students. The reservoir of Pau dos Ferros, shallow , turbid and eutrophic showed dominance of the functional group SN throughout the sample period . The phytoplankton biomass ranged from 20 to 70 mm ³ . L - 1, the lowest values coincided with the increase of the mixing zone and transparency, which contributed to the occurrence of a change in species composition phytoplankton . The application of the index Q proved relevant, the reservoir of Pau dos Ferros , depending on the species present , was classified ecologically as bad for almost the entire sample period . The reservoir Santa Cruz do Apodi showed low biomass ( 0.04 and 4.31 mm ³ . L - 1 ) and greater diversity in the phytoplankton composition . According to the index assembly (Q ), it showed moderate condition during most of the period influenced by different functional groups of typical meso- eutrophic environment (K S0, H1, C, F , J , E, D and N) . Associations of diatoms and green algae D and X1 succeeded populations of cyanobacteria in periods marked by greater instability in the system , caused by wind or rain. In summary , the occurrence of drought has a direct influence on the hydrological conditions of the reservoirs , in general, these events, reducing the reservoir level is directly related to decreased water quality and increased density of phytoplankton occurring predominance of cyanobacteria , the index Q reflected well to changes in phytoplankton composition , being a good indicator for biomonitoring of reservoirs in this study and survey of previous conceptions showed the need to work on environmental awareness for the preservation of water resources by conducting workshops for Environmental Education

Geomorfologia e neotectônica no Vale do Apodi-Mossoró RN

Numerous studies have indicated that the Potiguar Basin is affected by Cenozoic tectonics. The reactivation of Cretaceous fault systems affect the post-rift units, witch include Neogene and overlying Quaternary sediments. In this context, the objectives of this thesis are the followings: (1) to characterize the effects of post-rift tectonics in the morphology of Apodi Mossoró-river valley located in the central portion of the Potiguar, (2) to characterize the drainage of the Apodi Mossoró river valley and investigate the behavior of their channels across active faults, and (3) to propose a geologic-geomorphological evolutionary model for the study area. This study used a geological and geomorphological mapping of the central part of the basin, with emphasis on the Quaternary record, luminescence dating of sediments, and geoelectric profiles of the area. The results reveal by maps of structural lineaments and drainage channels of the rivers form valleys that are affected by faults and folds. In Apodi-Mossoró valley, anomalies of channel morphology are associated with the deformation of the post-rift basin. These anomalies show the reactivation of major fault systems in the Potiguar Basin in Cenozoic. On a regional scale, can be seen through the vertical electric profiles that the Cenozoic tectonics is responsible for the elevation of a macro dome NE-SE-trending 70-km long and 50km wide and up to 270 above sea level. In this sector, the vertical electric profiles data show that the contact between the Cretaceous and Neogene rise more than 100m. This Is an important feature of inversion data obtained in this work showed that the deposits that cover the macro dome (Serra do Mel) have ages of 119 ka to 43 ka. In the river valley and surrounding areas Apodi-Mossoró ages vary between 319 ka and 2.7 ka. From these data it was possible to establish the correct geochronological posiconamento paleodepósitos of distinguishing them from the fluvial deposits of the Neogene (Barreiras Formation)

Avaliação de impacto ambiental e gestão dos recursos natuarias no estuário Apodi Mossoró, nordeste do Brasil

The aim of this study is to investigate the eco-environmental vulnerability, its changes, and its causes to develop a management system for application of eco-environmental vulnerability and risk assessment in the Apodi-Mossory estuary, Northeast Brazil. This analysis is focused on the interference of the landscape conditions, and its changes, due to the following factors: the oil and natural gas industry, tropical fruits industry, shrimp farms, marine salt industry, occupation of the sensitive areas; demand for land, vegetation degradation, siltation in rivers, severe flooding, sea level rise (SLR), coastal dynamics, low and flat topography, high ecological value and tourism in the region and the rapid growth of urbanization. Conventional and remote sensing data were analyzed using modeling techniques based on ArcGIS, ER-Mapper, ERDAS Imagine and ENVI software. Digital images were initially processed by Principal Component Analysis and transformation of the maximum fraction of noise, and then all bands were normalized to reduce errors caused by bands of different sizes. They were integrated in a Geographic Information System analysis to detect changes, to generate digital elevation models, geomorphic indices and other variables of the study area. A three band color combination of multispectral bands was used to monitor changes of land and vegetation cover from 1986 to 2009. This task also included the analysis of various secondary data, such as field data, socioeconomic data, environmental data and prospects growth. The main objective of this study was to improve our understanding of eco-environmental vulnerability and risk assessment; it´s causes basically show the intensity, its distribution and human-environment effect on the ecosystem, and identify the high and low sensitive areas and area of inundation due to future SLR, and the loss of land due to coastal erosion in the Apodi-Mossoró estuary in order to establish a strategy for sustainable land use. The developed model includes some basic factors such as geology, geomorphology, soils, land use / land cover, vegetation cover, slope, topography and hydrology. The numerical results indicate that 9.86% of total study area was under very high vulnerability, 29.12% high vulnerability, 52.90% moderate vulnerability and 2.23% were in the category of very low vulnerability. The analysis indicates that 216.1 km² and 362.8 km² area flooded on 1m and 10m in sea levels respectively. The sectors most affected were residential, industrial and recreational areas, agricultural land, and ecosystems of high environmental sensitivity. The results showed that changes in eco-environmental vulnerability have a significant impact on the sustainable development of the RN state, since the indicator is a function of sensitivity, exposure and status in relation to a level of damage. The model were presented as a tool to assist in indexing vulnerability in order to optimize actions and assess the implications of decisions makers and policies regarding the management of coastal and estuarine areas. In this context aspects such as population growth, degradation of vegetation, land use / land cover, amount and type of industrialization, SLR and government policies for environmental protection were considered the main factors that affect the eco-environmental changes over the last three decades in the Apodi-Mossoró estuary.

Onde fica o sertão rompem-se as águas: processo de territorialização da ribeira do Apodi-Mossoró (1676-1725)

The Portuguese territorial process of the captaincy of Rio Grande was initiated in1598 with the conquest of the Potengi River bar by Mascarenhas Homem. This process lasted until 1633, when it was interrupted by the arrival of the Dutch, and resumed only in 1654. From this year on, the occupation of unknown lands of the captaincy was encouraged, supporting the advancement towards conquering the backlands, breaking the divisive boundaries with the captaincy of Siará Grande so far known: the Assú riverside. This breakthrough resulted in confrontations with the inhabitants of these lands, known as tapuias, leading to outbreak of several conflicts that composed the Barbarians War. The main stage of such events in Rio Grande, between the years 1687 and 1720, was precisely the Assú riverside, one of the spaces to be investigated by this research. Therefore, this paper aims to analyze the advance of the conquerors in Rio Grande, contributing to the territorial process, which resulted in the emergence of a new border between Rio Grande and Siará Grande: the Apodi-Mossoró river. For this purpose, it was used sources produced between the years 1659 and 1725, as the settlement letters, royal charters, correspondence between the City Council of Natal, captains of Rio Grande and the government of Pernambuco and also the general government, as well as the documents related to the militia composed mainly by Paulistas who struggled in the captaincy.

Política de atenção à saúde do idoso em Mossoró/RN: potencialidades e possibilidades para promoção do envelhecimento saudável no estado do Rio Grande do Norte

It discusses the Health Care of the Elderly in the town of Mossoró, traversing the paths that discussed the history of health care, which has been altered by the new (con) formation and required adjustments of society which led the development and implementation of the National Health Care for the Elderly with the backdrop of the guiding principles of the Health System - SUS. The goals outlined were: To map the implementation of the policy of health care for the elderly in Mossoró considering whether this is based on the principles and guidelines of the NHS and National Health Policy of the Elderly; Check if health promotion is seen as a strategy that favors the elderly mossoroenses the possibility of healthy aging; identify the discourse of the elderly about the aging process and the strategies you use to take care of your needs. Applies as a methodological strategy BOAS, complemented by interviews with twenty (20) elderly residents of Mossoró with a view to understand the objective elements, and the political and subjective traits that express a regularity which marks the area of health care mossoroense elderly. The data were tabulated and the BOAS divided into nine sections for analysis. The speeches were transcribed seized and subjected to a thorough reading that allowed the visualization of issues that have been examined with theoretical and methodological support to the model proposed by Boaventura de Souza Santos (2006) designated this cosmopolitan reason being supported by three meta-sociological procedures, namely, the sociology of absences, the sociology of translation work and emergencies. It appears as a result the exclusion and discrimination of the elderly in different social settings, a condition that prevents them from being aware of their importance as citizens deserving of decent treatment and respect for the family, society and the government, when addressing health the elderly said the need to propose alternative models of care that has the paradigm of health promotion. We conclude that in these areas, meetings are held, to draw lines that were heterogeneous because they were built by the dissimilarities that engender incessantly and show that although we have advanced regarding the attention of the elderly in Mossoró there is still a long way to go in order to meet the needs revealed by the elderly. It is suggested that the practice of trial-creation-differentiation, while highlighting the historical and procedural dimension, deconstructions and negotiations with collective effects. A democratic paradigm and analytical creeps: the constitution are moments of Health Care for the Elderly shaping a new landscape in the town of Mossoró.

Cartografia temporal e análise geoambiental da dinâmica da foz do Rio Piranhas-Açu, regiao de Macau-RN, com base em imagens Landast 5-MT

This work embraces the application of Landsat 5-TM digital images, comprising August 2 1989 and September 22 1998, for temporal mapping and geoenvironmental analysis of the dynamic of Piranhas-Açu river mouth, situated in the Macau (RN) region. After treatment using several digital processing techniques (e.g. colour composition in RGB, ratio of bands, principal component analysis, index methods, among others), it was possible to generate several image products and multitemporal maps of the coastal morphodynamics of the studied area. Using the image products it was possible the identification and characterization of the principal elements of interest (vegetation, soil, geology and water) in the surface of the studied area, associating the spectral characteristics of these elements to that presented by the image products resulting of the digital processing. Thus, it was possible to define different types of soils: Amd, AQd6, SK1 and LVe4; vegetation grouping: open arboreal-shrubby caatinga, closed arborealshrubby caatinga, closed arboreal caatinga, mangrove vegetation, dune vegetation and areas predominately constituted by juremas; geological units: quaternary units beach sediments, sand banks, dune flats, barrier island, mobile dunes, fixed dunes, alluvium, tidal and inundation flats, and sandy facies of the Potengi Formation; tertiary-quaternary units Barreiras Formation grouped to the clayey facies of the Potengi Formation, Macau Formation grouped to the sediments of the Tibau Formation; Cretaceous units Jandaíra Formation; moreover it was to identify the sea/land limit, shallow submersed areas and suspended sediments. The multitemporal maps of the coastal morphodynamics allowed the identification and a semi-quantitative evoluation of regions which were submitted to erosive and constructive processes in the last decade. This semi-quantitative evoluation in association with an geoenvironmental characterization of the studied area are important data to the elaboration of actions that may minimize the possible/probable impacts caused by the implantation of the Polo Gas/Sal and to the monitoring of areas explorated by the petroleum and salt industries

Educação Superior e o Ensino a Distância : Percepção dos Discentes e tutores sobre o Ensino Presencial e Semipresencial de uma IES em Mossoró - RN

A inquietação maior desse trabalho foi compreender de que maneira tutores e alunos participantes da modalidade de Ensino a Distancia de uma IES em Mossoró, Rio Grande do Norte, Brasil, significam esse processo frente ao ensino presencial. A pesquisa foi realizada com 315 alunos, 3 tutores e 1 coordenador do NEaD da referida IES. Procedeu-se a aplicação de um questionário com os alunos e uma entrevista semi-estruturada com os tutores e coordenadores. A análise dos dados quantitativos foi orientada por meio do Software SPSS, versão 17.0; enquanto que a análise dos dados qualitativos foi realizada através da análise de conteúdo. Os resultados demonstram que apesar do material ser de fácil entendimento e o AVA demonstrar fácil compreensão ainda existe certa resistência na utilização do ensino a distancia dentro da estrutura curricular do ensino presencial. O contanto físico ainda é um dos pontos fortemente apontados. Embora a interação seja vista como algo fundamental e a participação dos alunos nesses momentos sejam evidenciadas, os alunos consideram a comunicação com seus pares como um fator não contribuinte para a sua formação. Apesar de a maioria afirmar que é importante ter contato com a modalidade EAD dentro da estrutura curricular do curso, mais da metade não é favorável a determinação que possibilita a utilização dos 20% EAD no ensino presencial, por intermédio da portaria nº 4.059, de 10 de dezembro de 2004 que regulamenta a oferta de carga horária a distância para os cursos ou disciplinas presenciais. Observou-se ainda que tais alunos não cursariam uma pós-graduação nessa modalidade de ensino EAD. Sendo melhor aceita como um suporte para o ensino presencial. Assim, sugere-se que muito se tem a evoluir para que se venha utilizar tal modalidade de maneira mais efetiva. Isso ocorre devido ao fato de tais alunos continuarem ligados a metodologia tradicional onde a figura do professor é mais presente. Porém é salutar buscar um maior aprofundamento do tema para que tal realidade acompanhe o processo evolutivo dessa modalidade de ensino tão presente nos nossos dias.

Negros misturados: um estudo de caso sobre identidades negras em Mossoró-RN

With more or less 213.000 habitants, Mossoró is the second more developed city from the Rio Grande do Norte. The town is proclamated like the land of freedom. To so far, exist four moments in your history related with the defence of freedom that is point like truthful from so proclamation. Suchlike happenings are the first female vote on Brazil, the resistance against the Lampião s band, the worman s mutiny and the slave release in 1883, five year before the Áurea law sanction. These happenings are commemorate yearly on setember with one big theatrical event called by the freedom high. Inside this contexto of exaltation to freedom, there is one black movement by name black and beautiful. Is the present dissertation, talked about the building of black identities between the black militants of Mossoró and the dwellers from the Santo Antônio district. With such approach, we intend to think about possibles differences or likeness, how the militants and dwellers from the refered district self-calleds like blacks or not. We are understanding black identity like one process to self-affirmation done by specificities of the social context and the individual particularity. This way, the identity change into one dynamic and contextual reality, gone always by one business process against the interaction of the social actors. So we search to discuss the specificities that involve the process to building of black identities in the city of freedom

De repente, tudo mudou de lugar: refletindo sobre metamorfose urbana e gentrificação em Mossoró-RN

This study aims at solidifying the theoretical bases to provide, above all, an explanation for this phenomenon which currently happens, with a scenario of social, political, economic and cultural transformations worldwide in medium cities. Nevertheless, because it has different dimensions from its transformation axes, gentrification comes with change, but also with the introduction of a new purpose in the space using and occupation, outlining in this context the identity of places from the formation of centralities with the presence of flows with social and economic dynamicsThe current forms of geographic space appropriation show the directions of the senses and ideological profile which recreates the meanings and uses of content and materials from descriptions of a historical past. However, today there is an economic context in the urban space which refers to a search of strategies for change, i.e., the acquisition of parameter aimed at meeting the demands of the relationship between capital and labor, which ends up overriding some actions for the specification of the transformation methods within the urban space to be explained by new needs and also by the agents from the value adding to their interests and investments. Thus, we assume that the appreciation/gentrification of urban spaces may or may not result from the building of a public space, since the dialogic structure as a place of political interaction externalize conflicts and disagreements in general; it keeps segregating spaces. As new spaces are transformed, the access to them tends to happen with particular restriction, whereas some places like parks, shopping malls, high-rise and horizontal condos are the scene for major professional and family events. In this context, the gentrification process is used to designate interventions in the urban environment, in certain city spaces which are considered central to public and private investments. A historical place is permitted to be presented as a scenario, a stage full of attractions, through the transformation process. Studying gentrification consists of an analysis of the underlying interests in the transformation of these areas, and especially of the assessment of the interest level in the private sector to partner in order to modify the landscape. Gentrification results from the transformation processes of capital, which influences the efforts and investments application in order to establish and achieve optimal economic growth, focusing on a location socio-culturally centered in the urban space. Thus, the urban social structure develops in the light of some questions that relate not only the cities growth but also environmental conditions it provides in cities like Mossoro, State of Rio Grande do Norte, Brazil 2005 a 2011.

Implementação da política de assistência social em Mossoró/RN : uma avaliação a partir dos centros de referência da assistência social

The current National Policy for Social Assistance (PNAS) is the instrument that regulates the organization and procedures of social-welfare actions. Developed and approved in 2004 since the Unified Social Assistance System (ITS) was crated in 2003, it reaffirms the democratic principles of the Social Assistance Organic Law (LOAS) focusing on the universalization of social rights and equality of rights when accessing the social-welfare system. In the SUAS point of view, the PNAS highlights the information, monitoring and evaluation fields for being the best way to assure the regulation, organization and control by the Federal Government paying attention to the principles of decentralization and participation. This political-institutional rearrangement occurs through the pact among all the three federal entities. The pact deals with the implementation of the task. It says that it has to be shared between the federal autonomous entities, established by dividing responsibilities. To the cities, considered as the smallest territorial unit of the federation and closer to the population, was given the primary responsibility, which is to feed and maintain the database of SUAS NETWORK and identify families living in situations of social vulnerability. In addition to these responsibilities, the cities that have full autonomy in the management of their actions, have the responsibility to organize the basic social protection and the special social protection, that using the Center of Social Assistance Reference (CRAS) and the Center of Specialized Social Assistance Reference (CREAS), are responsible for the provision of programs, projects and services that strengthen the family and community; that promote people who are able to enjoy the benefits of the Continuing benefit of Provisions (BPC) and transfer of incomes; that hold the infringed rights on its territory; that maximize the protective role of families and strengthen its users organization. In Mossoró/RN, city classified as autonomous in the social assistance management, has five units of CRAS that, for being public utilities, are considered the main units of basic social protection, since they are responsible for the connection between the other institutions that compose the network of local social protection. Also known as Family House, the CRAS, among other programs and services, offers the Integral Attention to Families Program (PAIF), Juvenile ProJovem Program, socio-educational coexistence services programs, as well as sending people to other public policies and social-welfare services network, provides information, among others. In this large field, social workers are highlighted as keys to implement the policy of social assistance within the city, followed by psychologists and educators. They should be effective public employees, as a solution to ensure that the provision of the services are to be continued, provided to the population living around the units. However, what we can find here is inattention to the standard rules of social assistance, which not only undermines the quality of programs and services, but also the consolidation of policy on welfare as public policy of social rights

Práticas clientelistas e dádivas como estratégias de hegemonia política: uma análise sobre o campo da saúde em Mossoró-RN

The reality experienced by many families and individuals who seek and require the services of the Unified Health System - SUS, the relationships between users, health professionals, and political representatives, establishes the core of the issue that guides the choice and interest of this study concerning the prominence of clientelist practices and gifts that permeate the health field. The research is based on the analysis and reflection of the intrinsic relationship between the health and political fields. It analyses the health field and its relationship with the dynamics and developments of the local political scenario relating it to the implementation of the Family Health Program and Community Health Agents Program (PACS/PSF health programs) in the city of Mossoró, State of Rio Grande do Norte which refers to the period 1991-2010; and falls into a methodological perspective of qualitative approach. The methodological tools and techniques used were based on semi-structured interviews, direct observation of the field, journalistic texts and documentary sources. The construction and questioning of the object of the research were based on theoretical contributions from authors discussing the social field and symbolic power: Bourdieu (2005); clientelist relationships and gifts from asymmetric exchanges: Rouland (1997), Lanna (1995), Martins (1999), Carvalho (1999), Diniz (1982); exercise of hegemony and political strategy from authors who analyse this subject: Gramsci (1995), Coutinho (1981), and Gruppi (1978). Furthermore, the research has established dialogues with authors who address the dynamics of Brazilian politics such as Baquero (2001) and Weffort (1993). The collected data were subjected to qualitative content analysis. The results showed that with the implementation of the PACS/PSF programs in the aforementioned city, the health field has established itself as a key scenario for the exercise of political hegemony of the factions that dominate this socio-political context, resizing clientelist practices, however, without modifying the power structures within this social scenario
